LookUpEdit PopUpWidth

I use VB.Net and I've been reading the post on the issue everyone is having, including me with trying to deal with PopUpWidth of the LookUpEdit Control.
I have version 8.1.4 and I can't seem to set the PopUpWidth less then 100
I have the following Code:
        Dim colList As LookUpColumnInfoCollection = Me.LookUpEdit1.Properties.Columns
        LinqServerModeSource1.QueryableSource = From cntry In mDC.vCustomerCountries _
                                                Order By cntry.Description _
                                                Select cntry.CountryID, cntry.Description
        Me.LookUpEdit1.Properties.DataSource = LinqServerModeSource1
        Me.LookUpEdit1.Properties.DisplayMember = "Description"
        Me.LookUpEdit1.Properties.ValueMember = "CountryID"
        Me.LookUpEdit1.Properties.ShowLines = True
        Me.LookUpEdit1.Properties.ShowFooter = False
        Me.LookUpEdit1.Properties.ShowHeader = False
        Me.LookUpEdit1.Properties.PopupWidth = 30
        Me.LookUpEdit1.Properties.ShowDropDown = ShowDropDown.Never
        Me.LookUpEdit1.Properties.NullText = String.Empty
        Me.LookUpEdit1.Properties.SearchMode = SearchMode.AutoComplete
        Me.LookUpEdit1.Properties.AutoSearchColumnIndex = 1
        ' Add two columns to the dropdown.
        ' A First Column to display the CountryID field's values.
        colList.Add(New LookUpColumnInfo("CountryID", "Country ID", 0, FormatType.None, String.Empty, False, HorzAlignment.Near))
        ' A Second Column to display the Description field's values.
        colList.Add(New LookUpColumnInfo("Description", "Description", 50, FormatType.None, String.Empty, True, HorzAlignment.Near))
Can you please tell me if you are going to add a new property to handel this automaticaly to the widh the the control itself. Such as (AutoPopUpWidth)
And can you please tell me if the (AutoHeight) is suppose to automaticaly set the height of the DropDown to show only the number of rows being displayed. It seems to be the what ever the (DropDownRows) is set to even if the data is less. Is this going to be fixed.
Thanks for a great product.

Hello Andy,
Thanks for your question. If you need to implement the auto width functionality for a pop-up window, use the code below:

Visual Basic
Private Sub LookUpEdit1_Popup(ByVal sender As Object, ByVal e As System.EventArgs) Handles LookUpEdit1.Popup  
    Dim Form As PopupLookUpEditForm = CType(CType(sender, IPopupControl).PopupWindow, PopupLookUpEditForm)  
    Dim w As Integer = 0  
    For Each i As LookUpColumnInfo In CType(sender, LookUpEdit).Properties.Columns  
        If i.Visible Then  
            w += i.Width  
        End If  
    Next  
    Form.Width = w  
End Sub

To set the height of a pop-up window, use the DropDownRows property.
I have attached a sample project, which demonstrates how to implement this. Please review it and let me know whether it Meets your requirements.
Thanks,
George.
